Parameter Comparison

Engineering Selection Recommendations

For SPMWHT541MP5WAVMS4 (LM561B Plus - Active Status):

This substitute is recommended as the primary replacement option for new production and design continuity. The part maintains identical electrical characteristics (2.95V forward voltage, 65mA test current) and optical properties (3000K color temperature, 120° viewing angle, 80 CRI) while delivering enhanced luminous flux performance (32 lm vs 28 lm at 65mA). The increased efficiency (167 lm/W vs 146 lm/W) provides superior light output without circuit modification. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance exceeds the RoHS Compliant status of the original part, meeting current regulatory requirements. The reduced seated height (0.80mm vs 0.90mm) offers improved PCB assembly clearance. Higher maximum current rating (180mA vs 150mA) provides additional design margin for thermal and electrical stress conditions.

For SPMWHT541MD5WAVMS2 (LM561B - Obsolete Status):

This equivalent part provides direct electrical and optical substitution with identical specifications. Suitable for inventory replacement and existing design support where supply of the original SPMWHT541MD5WAVKS2 is exhausted. The only functional difference is packaging format (Cut Tape & Digi-Reel vs Tape & Reel), which does not affect component performance or PCB assembly compatibility. Obsolete status indicates limited future availability; use only for short-term production runs or legacy system maintenance.

Compliance Considerations:

Both substitute parts maintain RoHS compliance (RoHS Compliant or ROHS3 Compliant) and MSL 2A rating, ensuring compatibility with standard manufacturing processes and moisture-sensitive device handling protocols. ECCN and HTSUS classifications remain consistent across all three parts.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP5WAVMS4 be used as a direct drop-in replacement for SPMWHT541MD5WAVKS2?

A: Yes. Both parts share identical forward voltage (2.95V), test current (65mA), color temperature (3000K), viewing angle (120°), and physical footprint (5630 package, 5.00 x 3.00mm). The SPMWHT541MP5WAVMS4 delivers higher luminous flux (32 lm vs 28 lm) without requiring circuit modifications. The reduced seated height (0.80mm vs 0.90mm) improves PCB clearance. No design changes are necessary for substitution.

Q2: What is the difference between SPMWHT541MD5WAVKS2 and SPMWHT541MD5WAVMS2?

A: These parts are parametrically equivalent with identical electrical and optical specifications. The only difference is packaging format: SPMWHT541MD5WAVKS2 is supplied in Tape & Reel (TR) format, while SPMWHT541MD5WAVMS2 is supplied in Cut Tape (CT) & Digi-Reel® format. Component performance is identical; selection depends on assembly equipment compatibility and inventory handling requirements.

Q3: Why does SPMWHT541MP5WAVMS4 have a higher maximum current rating (180mA vs 150mA)?

A: The SPMWHT541MP5WAVMS4 represents an enhanced version within the LM561B Plus product line with improved thermal and electrical characteristics. The higher maximum current rating reflects the part's capability to handle increased stress conditions. Standard operation remains at 65mA test current for all three parts; the higher maximum rating provides additional design margin and operational flexibility.

Q4: Is the increased luminous flux of SPMWHT541MP5WAVMS4 (32 lm vs 28 lm) compatible with existing circuit designs?

A: Yes. The increased luminous flux results from improved LED efficiency, not from higher operating current or voltage. Both parts operate at identical 2.95V forward voltage and 65mA test current. Existing circuits require no modification. The higher light output is a performance benefit with no compatibility concerns.

Q5: What is the significance of ROHS3 compliance on SPMWHT541MP5WAVMS4 compared to RoHS Compliant status on the original part?

A: ROHS3 represents an updated compliance standard with enhanced environmental and substance restrictions. ROHS3 Compliant status on SPMWHT541MP5WAVMS4 exceeds the RoHS Compliant requirement of SPMWHT541MD5WAVKS2, ensuring compatibility with current and future regulatory frameworks. This upgrade provides assurance for long-term product qualification and market acceptance.

Q6: Can these LED parts be used interchangeably in applications requiring specific color rendering?

A: Yes, all three parts maintain identical CRI (Color Rendering Index) of 80 and color temperature of 3000K (warm white). Color rendering characteristics are identical across SPMWHT541MD5WAVKS2, SPMWHT541MP5WAVMS4, and SPMWHT541MD5WAVMS2. Interchangeability is assured for color-critical applications.

Q7: What are the moisture handling requirements for these parts?

A: All three parts carry MSL (Moisture Sensitivity Level) rating of 2A with 4-week floor life. This indicates moderate moisture sensitivity requiring standard dry storage and handling protocols. Parts must be stored in moisture-controlled environments and used within specified floor life windows after package opening. No special handling beyond standard MSL 2A procedures is required.

Q8: Are there any thermal management differences between the substitute parts and the original?

A: All three parts maintain identical thermal resistance of 16°C/W. Thermal management requirements are equivalent. The SPMWHT541MP5WAVMS4 offers slightly improved thermal performance through reduced seated height (0.80mm vs 0.90mm), which may provide marginally better PCB heat dissipation in space-constrained applications.

Q9: Which substitute part should be selected for new product designs?

A: SPMWHT541MP5WAVMS4 is the recommended choice for new designs. This part carries Active product status, ensuring long-term availability and supply chain stability. Enhanced efficiency (167 lm/W), higher maximum current rating (180mA), and ROHS3 compliance provide superior design margin and regulatory assurance compared to the Not For New Designs status of the original part.

Q10: What inventory considerations apply when selecting between these parts?

A: SPMWHT541MP5WAVMS4 has significantly higher inventory availability (50200 pcs vs 857 pcs for the original part), ensuring reliable supply for production scaling. SPMWHT541MD5WAVMS2 offers intermediate availability (3015 pcs) as a secondary option. For long-term production planning, SPMWHT541MP5WAVMS4 provides the most secure supply position.
